I carried this lightweight stove for my entire thru-hike of the AT. I used it almost everyday for 5 months straight and never had a problem with this stove. I never used a wind shield and had great fuel efficiency with this little guy. One of the bees things I liked about this stove is that you can adjust the flame to cook pancakes or let er rip for just a straight boil. I mean serious controlled cooking can be done with this guy. No maintenance needed and still going strong after 2200 miles and another 120 with the wife couple months ago! GET IT!
